Description

[0001] The present invention relates to a sliding door according to the preamble of claim 1.

[0002] Sliding doors of the generic type are known from EP 3 608 494 A1. Further sliding doors of the prior art are shown in EP 3 940 179 A1 and WO 2019 / 179 853 A1. Sliding doors of the generic type and also of the type according to the invention are provided with a frame that can be aligned in a vertical position and a sash that is guided horizontally slidably within the frame relative to the frame thus aligned.

[0003] The sashes of such sliding doors can preferably also be designed as lift-and-slide sashes if they are vertically height-adjustable relative to the frame and are also horizontally movable. They are generally fitted with multiple panes of glass and preferably have a surrounding sash frame. Such lift-and-slide sashes can be designed so that at least the lower frame profile can be recessed into the floor, at least in one closed position. In this way, they allow for a virtually frameless appearance at the floor.

[0004] The lift / slide sash of such a sliding door is usually moved horizontally relative to the frame into an open or closed position by means of a drive housed in the frame.

[0005] The drive for moving the lifting / sliding sash is typically engaged and disengaged at the lifting / sliding sash itself when raising it to a moving position and lowering it to a lowering position. A disadvantage of this solution is the potential for malfunctions during the engagement process.

[0006] The object of the invention is therefore to constructively provide a height-compensating and essentially or completely airtight closure of the fold space in a simple manner.

[0007] The invention solves this problem through the subject matter of claim 1.

[0008] Accordingly, a sliding door will be created, which initially has the following features: a vertically alignable frame comprising at least two vertical and at least one upper and one lower horizontally oriented frame member, a lift-and-slide sash slidably guided in the frame, wherein the lift-and-slide sash is horizontally slidably guided in the frame in its vertical orientation, wherein the lift-and-slide sash is vertically height-adjustable between a lowered position and a travel position that is vertically higher relative to it, wherein the lift-and-slide sash has a sash frame formed from at least one lower horizontal sash frame profile, two vertical sash frame profiles and one upper horizontal sash frame profile, and wherein the lift-and-slide sash is horizontally displaceable by a travel drive, wherein a height-compensating coupling device is provided.through which the drive mechanism of the lifting / sliding sash is or remains connected to the lifting / sliding sash even during a vertical position adjustment.

[0009] This creates a sliding door with a lift / slide element and height-compensating drive unit, eliminating possible malfunctions during the coupling process of a carriage of the drive unit in the frame and the lift / slide sash.

[0010] According to claim 1, the coupling device further comprises a sealing flap that compensates for the height differences occurring in a rebate space, thereby reducing drafts in the rebate space that variably form between the upper cross member of the frame and the upper horizontal sash frame profile due to vertical movement between the lowering and sliding positions of the lift / slide sash. This provides a simple, height-compensating, essentially or completely airtight seal for the rebate space.

[0011] According to the characterizing feature of claim 1, it is provided that the coupling device is arranged between a carriage of the traversing drive and a sash frame connection, wherein the sash frame connection is attached to the upper horizontal sash frame profile of the lift / slide sash.

[0012] This results in a coupling device that is structurally simple in design and equally easy to manufacture, with defined kinematic pivot points.

[0013] According to the characterizing feature of claim 1, it is further provided that in the lowered position of the lift / slide sash, the part of the sealing flap in the rebate space which is attached to the sash frame connection is pivoted and lowered, while the end which is attached to the carriage remains in the stretched horizontal plane, so that the sealing flap extends in a plane inclined with respect to the horizontal plane in the rebate space, and seals the rebate space against drafts in this way.

[0014] In In a particularly preferred embodiment of the invention, the drive mechanism of the lift / slide sash is permanently coupled to the lift / slide sash. This permanent coupling results in a particularly reliable, height-compensating drive mechanism for a sliding door with a lift / rail sash.

[0015] Furthermore, according to another particularly preferred embodiment of the invention, the coupling device may include or have a kinematic scissor mechanism. The kinematic scissor mechanism enables the absorption of large vertical movements of the lifting / sliding sash, such as those that occur when raising and lowering the lifting / sliding sash, while simultaneously allowing only small horizontal movements between the carriage and the sash frame connection.

[0016] In a further particularly preferred embodiment of the invention, the long leg and the short leg form a "y" shape. This results in simple kinematics for the coupling device based on the four-bar linkage principle.

[0017] Furthermore, according to another particularly preferred embodiment of the invention, the locus of the pivot point of the sash frame connection can be assumed to be stationary, with the locus of the pivot point of the sash frame connection running approximately on a vertical line. This advantageously results in minimal horizontal movements between the carriage and the sash frame connection during a lifting or lowering movement of the sliding / lifting sash.

[0018] In a further particularly preferred embodiment of the invention, the forces required for raising and lowering the coupling device are also provided to be almost independent of any simultaneously applied horizontal loads. This means that the actuator, which is provided for raising and lowering the lifting / sliding sash, does not have to exert any or only a small additional force for moving the coupling device.

[0019] In a further particularly preferred embodiment of the invention, the lift-and-slide sash is supplied with power via the carriage, the carriage having a coupling point for an optional current collector which is operatively connected to busbars arranged in the frame via sliding contacts. This allows for simple and convenient operation of the movements of each lift-and-slide sash, which can be located in the respective lift-and-slide sash and is thus clearly assigned to a specific lift-and-slide sash.

[0020] Furthermore, according to another particularly preferred embodiment of the invention, the sealing flap can be attached to the kinematic scissor. This results in simple and reliable mounting of the sealing flap.

[0021] Furthermore, according to another particularly preferred embodiment of the invention, the sealing flap can be equipped with brush seals, especially on one or more circumferential edge regions or edges. This creates a structurally simple and highly effective seal for the sealing flap.

[0022] According to a further particularly preferred embodiment of the invention, the sash frame connection is positively locked to the upper horizontal sash frame profile in the sliding direction of the lift / slide sash by means of a locking bridge. The locking bridge results in particularly simple assembly and fixing of the sash frame connection to the upper horizontal sash frame profile.

[0023] In a further particularly preferred embodiment of the invention, the locking bridge may also have two bolt-like bolts connected to each other by a connecting tab. These bolts are slidably guided in the sash frame connection perpendicular to the direction of movement of the lift-and-slide sash and are designed to engage in two recesses provided in the upper horizontal sash frame profile. This secures or locks the sash frame connection to the upper horizontal sash frame mullion in the direction of movement of the lift-and-slide sash. This allows the sash frame connection to be secured against displacement in the direction of movement of the lift-and-slide sash without tools or direct line of sight by a downward movement of the locking bridge, and to be released using the reverse procedure.

[0024] According to a further particularly preferred embodiment of the invention, the sash frame connection is inserted into the grooves provided for this purpose in the upper horizontal sash frame profile. This also results in simple assembly of the sash frame connection.

[0025] The need is also solved by a coupling device for connecting a traversing drive of a lifting / sliding wing of a sliding door, wherein the coupling device is designed according to one of the related claims.

[0026] Further advantages, features, and details of the invention will become apparent from the following description, in which several embodiments of the invention are explained in more detail with reference to the accompanying figures. The invention is not limited to these embodiments but also includes embodiments not shown in the figures but falling within the claims.

[0027] They show: Figure 1: in a) a schematic representation of a sliding door with a lift / slide sash in lowered position and closed position, in b) the lift / slide sash made of Fig. 1a in the travel position and closed position, in c) the lifting and sliding wing from Fig. 1a in the travel position and displaced position, in d) the lifting-sliding wing from Fig. 1a in the travel position and open position, in e) the lifting / sliding sash from Fig. 1a in lowered and open positions; Figure 2: a top view in section of the lift / slide sash according to Fig. 1a oder Fig. 1b Figure 3: a side view in section of the lifting / sliding sash according to Fig. 1b , Fig. 1c oder Fig. 1d Figure 4: a) a spatial view of an embodiment of a sliding door according to the invention with a lift / slide sash and a drive mechanism for moving the lift / slide sash; b) a close-up from Fig. 4a in section with a connection according to the invention between a carriage and a lift / slide sash; in c) a spatial view of a section of an upper horizontal sash frame member of the lift / slide sash, onto which part of the connection according to the invention between the carriage and the lift / slide sash is mounted; in d) a spatial view of an embodiment of the connection according to the invention between the carriage and the lift / slide sash; in e) a spatial view of a section of an upper horizontal frame member and a carriage according to the invention; in f) a section enlargement from Fig. 4 .

[0028] The position and location designations used below, such as "on", "vertical", "horizontal", "right", "left", refer without further explanation to a vertical installation position in a wall / masonry opening.

[0029] Fig. 1a shows a sliding door that can be inserted into a wall opening or in Fig. 1 The frame 300 is also inserted and set. A sash is slidably guided within the frame 300. Here, the sash is designed as a lift-and-slide sash 1 as an example.

[0030] The 300 frame can be vertically aligned and after Fig. 1 vertically aligned. In The lift-and-slide sash 1 is slidably guided in the frame 300. This is in Fig. 1a shown in a closed position, in which the lift-and-slide sash 1 closes a passage D through the frame 300. In addition to the lift-and-slide sash 1 shown, - as in the Figuren 1a bis 1e As shown, a fixed glazing element 2 is provided. However, one or more additional lift / slide sashes 1 may also be arranged in the frame or in the wall opening (not shown).

[0031] Adjoining the wall opening at the bottom of the frame 300 is a horizontal guide channel 3, which extends below a floor level designated here as "OKFF" ("top edge of finished floor"). The lift-and-slide sash 1 can be lowered into a position as described in Fig. 1a shown, can be lowered into the guide channel 3, for example in such a way that in the lowered position a lower frame profile (not shown here, see Fig. 3 ) of the lifting / sliding sash 1 is not visible.

[0032] The lift-and-slide sash 1 can also be displaceable relative to and on a first, height-adjustable roller element 50. For this purpose, it can have a rail-like running surface on its underside.

[0033] The lift / slide sash 1 can be moved from a lowered position to a higher travel position by changing its height. This is achieved by changing the height of the first roller element 50, which is located in Fig. 1b , Fig. 1c und Fig. 1d As shown, and briefly described by way of example, the lift / slide sash 1 can be moved from the guide channel 3 – i.e., from a lowered position – into a travel position at the finished floor level (FFL). From the travel position, the lift / slide sash 1 can be moved out of the position shown in the diagram. Fig. 1a The depicted closed position is transformed into a displaced position that opens passage D here - as in Fig. 1d The process is described below. For this purpose, the guide channel 3 has a second roller element 60, which is aligned with the first roller element 50. A height adjustment drive may also be provided (not shown here). Fig. 1c Figure 1 shows how the lift-and-slide sash 1, in its moving position, has left the closed position and moved towards the fixed glazing 2. Part of the lift-and-slide sash 1 is guided on the first roller element 50, and another part of the lift-and-slide sash 1 is guided on the second roller element 60, as shown in Figure 2. Fig. 1e shown - optionally also able to change its elevation.

[0034] In Fig. 1d The lifting / sliding sash 1 has reached the open position in its travel position. Fig. 1e The illustration shows that the lift / slide sash 1 can optionally be lowered into a lowered position in the open position.

[0035] In Fig. 2 is a top view in section of the lifting / sliding sash 1 according to Fig. 1a oder Fig. 1b As shown, a frame 300 is inserted into the wall opening. This frame preferably has at least two vertical and two or more horizontally oriented frame mullions in a vertical orientation. Fig. 2 The two lateral vertical frame members 310, 320 are shown. A central vertical frame member 350 is also shown in section, which may belong to a fixed surface element, preferably to the fixed glazing 2.

[0036] Furthermore, a floor beam 330 – also called a threshold or clamp beam – is shown. This can, for example, be designed with its upper edge flush with the finished floor level (FFL) – in order to enable advantageous barrier-free access – and thus be completely accommodated by the guide channel 3.

[0037] The left vertical frame member 310 and the right vertical frame member 320 can each have two shells 311, 312 and 321, 322 respectively, which are connected to each other via insulating webs 313, 323. The shells 311, 312 and 321, 322 can be connected as shown in Fig. 2 The shells shown are made from geometrically identical profiles. This is advantageous but not mandatory. The shells 311, 312 and 321, 322 may have one or more hollow chambers. The insulating webs 313, 323 are preferably made of a plastic material. The shells 311, 312 and 321, 322 are preferably made of a light metal by an extrusion process. Alternatively, the shells 311, 312 and 321, 322 may also be made of a different material and / or by a different manufacturing process.

[0038] The lateral vertical frame members 310, 320 of the frame 300 thus formed each have an E-shaped cross-sectional geometry, which are arranged in a mirror image to each other in the formed frame 300. A first left rebate space 314 and a second left rebate space 315 as well as a first right rebate space 324 and a second right rebate space 325 can each be closed with a snap-in cover profile 316, 326.

[0039] In the example of the Fig. 2 In the fixed glazing area 2, the second right rebate 325 of the right vertical frame member 320 is closed with the cover profile 326, while in the lift-and-slide sash area 1, the first left rebate 314 of the left vertical frame member 310 is closed with the cover profile 316. The cover profile 316, 326 is preferably made of a light metal by an extrusion process. Alternatively, the cover profile 316, 326 can also be made of a different material and / or by a different manufacturing process.

[0040] The fixed glazing 2 is inserted into a frame 200. The rebate spaces 211, 221 of the frame 200 are sealed against the environment with elastic seals that conform to the fixed glazing 2.

[0041] The frame 200 of the fixed glazing 2 shows a left vertical frame profile 210 and a right vertical frame profile 220. The frame of the fixed glazing 2 may have additional frame profiles. For example, an upper and a lower frame profile (not shown here) are conceivable. The frame profiles 210 and 220 are preferably made of a plastic material by an extrusion process. Alternatively, the frame profiles 210 and 220 can also be made of a different material and / or by a different manufacturing process.

[0042] The fixed glazing 2 engages with its right vertical edging profile 220 of the edging frame 200 in the second right rebate space 325 of the right vertical frame mullion 320. The resulting gaps between the edging profile 220 and the rebate space 325 are each sealed with a sealing profile.

[0043] The fixed glazing 2 further engages with its left vertical edging profile 210 in a rebate space 351, which is formed by the centrally arranged vertical frame member 350. The centrally arranged vertical frame member 350, together with the cover profile 316, which closes the first left rebate space 314 in the area of ​​the left vertical frame member 310, defines the opening D.

[0044] A retaining profile 352 is inserted into the rebate 351 of the centrally arranged vertical frame member 350 and preferably firmly connected to the frame member 350. This firm connection can be achieved by a material bond, such as adhesive bonding. The left vertical retaining profile 210 of the frame 200 of the fixed glazing 2 is inserted into the retaining profile 352 and firmly connected to it via one or more positive locking connections. The resulting gaps are sealed by appropriate sealing profiles.

[0045] A surface element – ​​here designed as glazing – of the lift / slide sash 1 is inserted into a sash frame 100. The rebate spaces 111, 121 of the sash frame 100 are sealed against the environment with elastic seals that conform to the surface element.

[0046] Of the sash frame 100 of the surface element of the lift-and-slide sash 1, a left vertical sash frame profile 110 and a right vertical sash frame profile 120 are shown here. The sash frame of the glazing of the lift-and-slide sash 1 can have further sash frame profiles. For example, an upper horizontal sash frame profile 140 and a lower horizontal guide frame profile would be conceivable (neither shown here, see [reference]). Fig. 3 The sash frame profiles 110, 120, 140, 150 are preferably manufactured from a plastic material by an extrusion process. Alternatively, the sash frame profiles 110, 120, 140, 150 can also be manufactured from a different material and / or by a different manufacturing process.

[0047] The surface element of the lift-and-slide sash 1 engages with its left vertical sash frame profile 110 in the second left rebate 315 of the left vertical frame mullion 310. The left vertical sash frame profile 110 may be fitted with a protective cap 111, which is snapped onto the sash frame profile 110. The resulting gaps between the sash frame profile 110 and the rebate 315 are each sealed with a sealing profile.

[0048] The surface element of the lift / slide sash 1 further engages with its right vertical sash frame profile 120 in a rebate space 131, which is formed by a finishing profile 130.

[0049] A retaining profile 132 is inserted into the rebate 131 of the end profile 130 and preferably firmly connected to the end profile 130. This firm connection can be achieved by a material-bonded connection, such as gluing. The right vertical sash frame profile 120 of the surface element of the lift / slide sash 1 is inserted into the retaining profile 132 and firmly connected to the retaining profile 132 via one or more positive-locking connections. The resulting gaps are sealed by appropriate sealing profiles.

[0050] In Fig. 3 A side view of the lift / slide sash 1 is shown in section. The bottom mullion 330 and an upper cross mullion 340 of the frame 300 are shown here.

[0051] The upper cross member 340 can be similar to the left vertical frame member 310 (see Fig. 2 ) and the right vertical frame member 320 (see also Fig. 2 ) be constructed. This is advantageous, but not mandatory. In contrast to the vertical frame members 310, 320, the upper cross member 340 has at least one or – as in Fig. 3 shown - several guide surfaces 343, 344.

[0052] The guide surfaces 343, 344 are part of a guide bearing 40 of the lifting / sliding sash 1. It should be noted here that the guide bearing 40 of the lifting / sliding sash 1 merely guides it along the guide surfaces 343, 344 when it is moved from the closed position to the open position, but does not bear any load, i.e., in particular, it does not absorb the weight of the lifting / sliding sash 1. Accordingly, the guide bearing 40 acts as a floating bearing with respect to the movement of the lifting / sliding sash 1.

[0053] The guide bearing 40 can have one or more carriages 41, on which at least one or more – here two – guide rollers 42, 43 are rotatably mounted. These rollers can roll on the guide surfaces 343, 344 and thereby guide the lift / slide sash 1 in its upper area during movement. The lift / slide sash 1 can thus also have a guide in its upper area relative to the frame 300 and a drive mechanism 600 (not shown here, see [reference]). Fig. 4a exhibit.

[0054] A belt lock 46 can be integrated into the respective carriage 41, with which a traction element (not shown here, see Fig. 4a und 4b ) of a traction gear on the carriage 41 is fixed, so that the carriage 41 can be moved actuated via the traction gear.

[0055] The surface element of the lift-and-slide sash 1 engages in a rebate of the upper horizontal sash frame profile 140 and is sealed against the environment by sealing profiles. Furthermore, the surface element of the lift-and-slide sash 1 is sealed to a rebate 345 of the second shell 342 of the upper horizontal frame mullion 340 by two brush seals 346, 347. This creates a flexible, robust, and effective seal with respect to vertical movement of the lift-and-slide sash 1, which occurs when the lift-and-slide sash 1 is raised from the lowered position to the sliding position and vice versa when lowered from the sliding position to the lowered position.

[0056] The rebate space 348 of the first shell 341 is closed in the area of ​​the passage D here by a snap-in cover profile 349.

[0057] The 330 floor rail can - as in Fig. 3 shown - analogous to the left vertical frame member 310 (see Fig. 2 ) and the right vertical frame member 320 (see also Fig. 2 ) be structured. This is advantageous, but not mandatory.

[0058] Accordingly, the floor beam 330 can have two shells 331, 332, each connected to the other via an insulating web 333. The shells 331, 332 can be connected as shown in Fig. 3 The shells 331 and 332 are shown to be made from geometrically identical profiles. This is advantageous but not mandatory. The shells 331 and 332 can have one or more hollow chambers. The insulating web 333 is preferably made of a plastic material. The shells 331 and 332 are preferably made of a light metal by an extrusion process. Alternatively, the shells 331 and 332 can also be made of a different material and / or by a different manufacturing process.

[0059] The resulting bottom rail 330 of the frame 300 has an E-shaped cross-sectional geometry. A left rebate 334 is closed here with a snap-in cover profile 335, which forms the bottom of the opening D. A right rebate 336 accommodates the first height-adjustable roller element 50 and the second roller element 60.

[0060] The floor beam 330 is preferably inserted into the guide channel 3 in such a way that the floor beam 330 is completely received by the guide channel 3 and is therefore advantageously not visible from the outside.

[0061] In the Fig. 4a The upper section of the sliding door is shown with a lift / slide sash 1, which is preferably designed here as a lift / slide element.

[0062] For moving the lifting / sliding sash 1, a traversing drive 600 can be provided, which includes an actuator that acts on the lifting / sliding sash 1 via a traction element. The actuator is preferably designed as an electric motor, while the traction element is preferably designed as a toothed belt. The traction element is preferably attached to the carriage 41 by the belt lock 46. The traversing drive 600 can also include a gearbox. The traversing drive 600 can be controlled by a control unit, the actuating device of which is preferably mounted on or in the sash frame 100 of the lifting / sliding sash 1 (not shown here).

[0063] The illustration shows the drive unit 600 of the lift-and-slide sash 1 and a height-compensating coupling device 500, which is arranged between the carriage 41 of the drive unit 600 and the upper horizontal sash frame profile 140 of the lift-and-slide sash 1 and connects them. The toothed belt of the drive unit 600 of the lift-and-slide sash 1 can be attached to the carriage 41 by means of the belt lock 46. A locking device 400 is also shown, with which the lift-and-slide sash 1 can be locked against movement in the horizontal direction.

[0064] In Fig. 4b Is the coupling device 500 from Fig. 4a Shown enlarged. The coupling device 500 connects the carriage 41 to a sash frame connection 502 via a kinematic scissor mechanism 501. Preferably, the coupling device 500 connects the carriage 41 permanently via the kinematic scissor mechanism. Thus, the coupling device 500 connects the drive unit 600 to the lift-and-slide sash even during vertical position adjustment of the lift-and-slide element.

[0065] The kinematic scissor mechanism 501 creates a vertically movable coupling device 500 that bridges the rebate 345 between the lift / slide sash 1 and the carriage 41, which results in the lowered position of the lift / slide sash 1. This eliminates error-prone coupling processes between the carriage 41 and the respective lift / slide sash 1, as required according to the prior art.

[0066] The kinematic scissor mechanism 501 thus enables the absorption of large vertical movements of the lifting / sliding sash 1, such as those that occur when lifting and lowering the lifting / sliding sash 1, while simultaneously allowing for small horizontal movements between the carriage 41 and the sash frame connection 502.

[0067] In this way, a permanent coupling is created between the lifting / sliding sash 1 and the carriage 41 of the drive of the lifting / sliding sash 1, which is characterized by a safe power transmission and defined end positions even in the case of structural conditions that change over time.

[0068] The kinematic scissor mechanism 501 can have a long leg 503 and a short leg 504. The long leg 503 can be pivotally connected to the sash frame connection 502 and slidably connected to the carriage, with the sliding direction of the long leg 503 being parallel to the sliding direction of the lift / slide sash 1, as shown by way of example in the Figuren 4e und 4f The short leg 504 can be pivotally connected to the long leg 503 and to the carriage 41. The long leg 503 and the short leg 504 thus preferably form a kind of "y". This preferably results in three fixed pivot points: one in the carriage 41, one in the sash frame connection 502, and one between the long leg 503 and the short leg 504, as well as a sliding connection between the long leg 503 and the carriage 41.

[0069] With the carriage 41 assumed to be stationary, the trajectory of the pivot point of the sash frame connection 502 thus runs approximately on a vertical line. This results in advantageously small horizontal movements between the carriage 41 and the sash frame connection 502 during a lifting or lowering movement of the lift / slide sash 1.

[0070] The forces required for lifting and lowering are therefore almost independent of any simultaneously applied horizontal loads.

[0071] It can be provided that the lift-and-slide sash 1 is supplied with power via the carriage 41. For this purpose, the carriage 41 has a coupling point for an optional current collector, which is operatively connected to busbars arranged in the frame via sliding contacts. Since the carriage 41 moves synchronously with the lift-and-slide sash 1, a simple cable connection can then be established from the sliding contacts via the kinematic scissor mechanism 501 and the carriage 41 to the sash frame connection 502. The busbars can be supplied with power via feed contacts in the upper cross member 340 of the frame 300. For details of the power supply to the lift-and-slide sash 1 via sliding contacts and busbars, reference is made to DE ...

[0072] The coupling device 500 has a sealing flap 505. The sealing flap 500 can be attached to the kinematic scissor 501 (see in particular). Fig. 4d ).

[0073] The sealing flap 505 can, in the raised position of the lift / slide sash 1, essentially lie or be aligned in a spanned horizontal plane, i.e., in relation to the respective coordinate system in Fig. 4a und Fig. 4b in an xz-plane or parallel to the xz-plane.

[0074] In the lowered position of the lift / slide sash 1, according to the invention, the part of the sealing flap 505 which is attached to the sash frame connection 502 is lowered in the rebate space 345, while the end which is attached to the carriage 41 remains in or parallel to the xz-plane, so that the sealing flap 505 extends in a plane inclined with respect to the xz-plane in the rebate space 345, as shown in Fig. 4a und Fig. 4b is shown and preferably seals the fold space 345 completely or substantially against drafts or significantly reduces them.

[0075] The sealing flap 505 can be dimensioned such that the rebate space 345 is also perpendicular to the plane of the surface element or the glazing - i.e. in the direction of the z-axis with respect to the respective coordinate system in the Figuren 4a und 4b - can be sealed.

[0076] If the sealing flap 505 is attached to the kinematic scissor 501, the sealing flap 505 preferably extends parallel to the long leg 503 of the kinematic scissor 501, as shown in Fig. 4b and 4d As shown. Since the long leg 503 of the kinematic scissor 501 also extends in or parallel to the xz-plane in the raised position of the lifting / sliding sash 1, the sealing flap 505 also extends in this plane when the lifting / sliding sash 1 is in the raised position and in an inclined plane to the xz-plane when the lifting / sliding sash 1 is in its lowered position.

[0077] The sealing flap 505 thus compensates for any height differences that occur in the rebate space 345, which forms between the upper cross member 340 of the frame 300 and the upper horizontal sash frame profile 140 due to vertical movement between the lowering and sliding positions of the lift / slide sash 1. In this way, the sealing flap 505 ensures the airtightness of the rebate space 345 in every position of the lift / slide sash 1. In its angled position, the sealing flap 505 effectively seals the entire or substantially the entire cross-section of the gap in the rebate space between the upper sash frame member and the lower edge of the upper vertical frame member, which widens and narrows during lifting and lowering. Lateral sections of the frame members or other devices can then additionally seal this gap or rebate space, which is essentially rectangular in cross-section.To achieve optimal sealing, the sealing flap 505 can be equipped with brush seals 506.

[0078] It may also be provided that the sash frame connection 502 is fixed to the upper horizontal sash frame profile 140 in the sliding direction of the lift / slide sash by means of one or more locking bridges 507, as is the case in the Figuren 4b , 4d and especially in Fig. 4c is shown.

[0079] The locking bridge 507 has at least one, or in this case two, bolt-like bolts 508a, b, which are connected to each other in a bridge-like manner by a connecting tab 509. The bolts 508a, b are slidably guided in the sash frame connection 502 perpendicular to the direction of movement of the lift / slide sash 1 and are designed to engage in two recesses 510a, b, which are provided in the upper horizontal sash frame profile 140, in order to positively lock or secure the sash frame connection 502 to the upper horizontal sash frame mullion in the direction of movement of the lift / slide sash.

[0080] The locking bridge 507 enables particularly easy assembly and fixing of the sash frame connection 502 to the upper horizontal sash frame profile 140, as shown in Fig. 4d The sash frame connection 502 is inserted into the grooves 511a, b of the upper horizontal sash frame profile 140 when the lift / slide sash 1 is raised, and can then be secured against displacement in the direction of movement of the lift / slide sash 1 by a downward movement of the locking bridge 507 without tools and without direct visual contact, and can also be released again using the reverse procedure.
